Experimental studies, using albino rabbits, showed that following the sensitization with histamine and homologous liver antigen conspicuous liver injury, closely resembling chronic active hepatitis, which progressed into liver cirrhosis with pseudolobulus formation, could be induced. The splenic weight, obtained after the administration of several hepato-toxic substances, had intimate relation with serum gammaglobulin levels. Furthermore, in a group in which splenectomy was performed after the development of hypergammaglobulinemia, serum gammaglobulin resulted in a rebound increase in comparison with extremely low level of serum gammaglobulin in a group in which splenectomized prior to sensitization. These results may suggest that (1) autoallergic mechanism should never be ignored. (2) splenomegaly in chronic liver diseases should not be considered from hemodynamic disturbance alone, but one of the important reacting sites where many factors including antigen antibody reaction are involved.

A short survey is given on description and evaluation of progress and developmental trend of laparoscopy. Important technical improvements are the cold light via the glass fibre light conductor, optics of high value, the colour photography with electronic flash-light, colour films and colour television, new accessory instruments and belongings. Now as ever hepatomegaly and splenomegaly, jaundice, ascites, portal hypertension, suspicion of cirrhosis and metastases are regarded as main indications. The laparoscopy deserves a greater consideration in unclear abdominal symptoms, in gynaecological diseases, for the proof of the affection of liver and spleen in lymphogranulomatosis, sarcoidosis, tuberculosis (with aimed liver biopsy). The endoscopic retrograde cholangiopancreatography in the differential diagnosis of the jaundice competes with the laparoscopy, but it is not able to supersede it. The laparoscopic judgment of the pancreas and the importance of visible changes of the fine structed. Among the contraindications of the laparoscopy the hiatal hernia has lost its significance.

This paper gives, in detail, the causes of either liver disease or hepatomegaly in 100 patients, mostly adults, admitted to the medical wards of Angau Memorial Hospital, Lae, during 1968 and 1969. The major findings included liver cell carcinoma, cirrhosis (often with chronic active hepatitis), tropical splenomegaly, pericholangitis and hepatitis. There were 27 with miscellaneous findings including ten with normal, or almost normal, livers despite the definite enlargement. Patients with liver cell carcinoma presented late in the course of their illness and had a poor prognosis. Others, with pericholangitis, had clinical features of portal hypertension indistinguishable from that complicated cirrhosis. There was an unexpected number with chronic active hepatitis and a liver biopsy is essential for such a diagnosis. Hepatic sinusoidal lymphocytosis is almost invariably found in patients with TS but may occasionally be found in those with a non-palpable spleen. Patients with right heart failure of chronic respiratory disease, and jaundice of acute pneumonia were excluded from the study.

Increased splenic uptake of radiocolloids is a helpful sign in the scintigraphic diagnosis of various hepatocellular diseases, but little attempt has been made to quantify this physiologic phenomenon. We have devised a simple computer method that compares average splenic activity to average right-lobe liver activity. The method is reproducible (r = 0.97) and exhibits little interobserver variation (r = 0.99). One hundred clinically normal subjects were found to have a nearly symmetrical distribution of S/L ratios around a mean of 0.77, with a s.d. of 0.20. Fifteen subjects normal by biopsy were found to have a similar mean spleen-to-liver (S/L) ratio of 0.74. Based upon a normal range of 0.37 to 1.17 (0.77 +/- 2 s.d.), elevated S/L ratios were found in fatty metamorphosis (85%), cirrhosis (67%), and chronic hepatitis (43%). Abnormal S/L ratios in the range from 1.17 to approximately 1.4 were not visually obvious. Overall sensitivity of the S/L ratio in these three diseases is 69%. When combined with the other scintigraphic indications of hepatocellular disease (nonhomogenous colloid uptake, hepatomegaly, splenomegaly, and bone-marrow colloidal uptake), the liver scan was found to have a sensitivity of 93%.

A wide spectrum of clinical and morphologic changes in 32 autopsy cases of noncirrhotic portal fibrosis have been described. The disease frequently occurs in younger patients with a long history of splenomegaly, usually with a history of hematemesis. Females are affected almost equally as often as males in contrast to cirrhosis. The patients tolerate the bleeding episodes well. Death is usually due to massive hemorrhage. The diagnosis is achieved through a process of exclusion. A critical analysis of hemodynamic data, a splenoportogram, liver function tests (particularly Bromsulphalein retention) and angiographic data is mandatory. Needle biopsy of the liver appears to have limited value in making the diagnosis. The gross anatomic findings vary from a nearly normal liver to gross nodularity, seen particularly on the posteroinferior surface. In some cases these nodules are seen to physically impede the portal blood flow and contribute to portal hypertension. Phlebosclerosis of the smaller radicles of the portal vein and irregular scarring are the outstanding morphologic features of the disease. These changes are usually associated with irregular dilatation of some of the larger intrahepatic branches of the portal vein as well as fibroelastosis with or without occluding or organizing thrombi in both intra- and extrahepatic branches of the portal vein. The changes in hepatic venous radicles are characterized by irregular sclerosis, which seems to contribute significantly toward postsinusoidal block in advanced cases. The probable mode of evolution is discussed.

Extra-hepatic obstruction of the portal vein is a well known cause of hypertension in childhood and 55 out of the 97 patients (57 per cent) seen with this condition presented before they were 15 years old. However, nearly half our cases (43 per cent) presented in adult life. Haematemesis was the commonest mode of presentation in both the adult and childhood group although splenomegaly was common, especially in the children. The severity and frequency of haematemesis increased during puberty in the children. Twelve children and three adults have now not bled for between five and 30 years, 10 of them ceasing spontaneously and five following surgery. Intra-abdominal infection or septicaemia precipitated the portal venous obstruction in 38 patients (39 per cent), though the exact cause of such obstruction in patients who had no cirrhosis was obscure in about half the cases. Ascites was present in 18/51 (35 per cent) of the children and 24/35 (69 per cent) of the adults. Its presence was associated with an increased mortality (p less than 0.01). Nineteen out of 42 (45 per cent) patients with ascites also had portal-systemic encephalopathy. Twenty-four patients died, nine having presented during childhood, variceal haemorrhage was responsible for death in 19 and infection in five. Sixty-four patients underwent 114 operations for variceal haemorrhage. Mortality was greater in the surgical group compared with those managed conservatively. Surgery is therefore indicated only in the rare case where bleeding cannot be controlled by medical means.

A statistical survey of the necropsy population, for the year 1973, at the Veterans Administration Hospital, Long Beach, Calif, was performed to determine changes occurring in the spleen. When cirrhosis of the liver was present, spleens were usually enlarged but not substantially firmer. In cases in which there was no cirrhosis, severe systemic infection was not accompanied by splenomegaly, although spleen softening was present. Generally, spleen size did not appear to be related to its own consistency. However, when cirrhosis of the liver was present, severe infection was accompanied by a decrease in the size of the spleen, with no change in consistency; but in these cases, there was less infection at the time of death. Splenomalacia was not shown to be related to postmortem autolysis. The spleen weight decreased only slightly with aging.

Alcohol-related disturbances are seen against the three blood cell systems. They appear after important alcohol consumption within few days and are independent from the existence of liver cirrhosis with splenomegaly. They are promptly and completely reversible after interruption of alcohol supply. Disturbances in erythropoiesis are manifested in bone marrow with megaloblasts, ring sideroblasts, and vacuoles in cytoplasma and nucleus of nucleated red cells. They are caused by folate deficiency and by perturbations of iron utilization, which is perhaps connected with impaired heme synthesis following pyridoxal phosphate deficiency. Serum iron generally increases during alcohol consumption and decreases in the following alcohol-free period. The anemia may be macrocytic and normochromic or dimorphic with hypochromic microcytes. Anemias of hard alcohol drinkers are observed also as consequence of bleeding or hemolysis of different causes. The lability against infections of drinkers is associated with changes in granulopoiesis. The most important findings are granulocytopenia, vacuoles in the immature marrow cells, perturbations in granulopoietic maturation, and decrease of marrow response. Frequently, alcohol drinkers demonstrate thrombocytopenia which is caused by ineffective thrombopoiesis and by shortened life span of platelets as direct effect of ethanol. Functional impairments of thrombocytes have been published, too.

A reaction of the RES with its organs (lymph nodes, spleen, bone marrow and Kupffer's cells) is not uncommon in rheumatoid arthritis. Although these manifestations are pronounced in Felty's syndrome, reviewing articles about Felty's do not mention liver manifestations. This paper summarises the publications about liver findings in Felty's syndrome. Hepatomegaly, abnormal bromsulfalein tests, raised alkaline phosphatase and transaminases have been stated in many case reports. Among 34 patients, the frequency of hepatomegaly was 68%, of abnormal bromsulfalein tests 27%, of alkaline phosphatase 23% and of transaminases 18%, respectively (52). Alkaline phosphatase and transaminases were raised in almost all of 12 patients (3). The histological correspondence is an infiltration with lymphocytes of sinusoids and portal fields, a portal fibrosis and occasionally a cirrhosis. These histological abnormalities, as well as enlarged lymph nodes and splenomegaly, have to be considered as organic manifestations of rheumatoid arthritis. If the nodular regenerative hyperplasia of the liver, which has been reported also after use of contraceptives, is a manifestation of Felty's syndrome, remains unresolved.
